In recent weeks Defense Secretary James Mattis and other Defense Department officials have been working to determine what level of added support -- possibly as many as 5,000 extra troops -- would be needed to stabilize Afghanistan’s security forces.

The Pentagon had been pledging a plan for Afghanistan by the middle of this month.

“We are not winning in Afghanistan,” Mattis told the Senate Armed Services Committee last month.

Currently 8,400 U.S. troops are in Afghanistan, training and advising local security forces.

Earlier this year, NATO leaders also agreed to send additional forces into the country.

Pentagon officials were said to be hopeful that Trump’s support for military might to achieve U.S. goals, combined with his hands-off management, would help end the Afghan war.

Trump gave Mattis the go-ahead several weeks ago to raise troop levels in Afghanistan by as many as 3,900, but Mattis has yet to deploy the extra personnel.

Earlier this week, Trump met with service members who served in Afghanistan and suggested he was losing patience with the conflict.
